Before this change backend integration tests depended on each other,
so tests could not be retried.
After this change we nest tests to ensure that tests are provided with
the starting state they expect.
Tell the integration test runner that it can retry backend tests also.
This also includes bin/test_independence.go which runs each test
individually for a backend to prove that they are independent.
Before this change TestPurge would remove a container and subsequent
tests would fail because the container was still being deleted so
couldn't be created.
This was fixed by introducing an fstest.NewRunIndividual() test runner
for TestPurge which causes the test to be run on a new container.
- Make integration tests use a config file
- Output individual logs for each test
- Make HTML report and open browser
- Optionally email and upload results
Sometimes pcloud will leave a half uploaded file when the transfer
actually failed. This patch deletes the file if it exists.
This problem was spotted by the integration tests.
This change to go1.11 causes the TestFsPutError test to fail
https://go-review.googlesource.com/c/go/+/114316
This is because it now passes the half written file to the backend
whereas it didn't previously because of the buffering.
In this commit the size of the data written was increased to 5k from
50 bytes to provoke the test failure under go1.10 also.

Google cloud storage doesn't normally need retries, however certain
things (eg bucket creation and removal) are rate limited and do
generate 429 errors.
Before this change the integration tests would regularly blow up with
errors from GCS rate limiting bucket creation and removal.
After this change we low level retry all operations using the same
exponential backoff strategy as used in the google drive backend.
- make Close permanent and return errors afterwards
- use RangeSeek from the wrapped reader if present
- add a limit to chunk growth
- correct RangeSeek interface behavior
- add tests
